DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to detergent mixtures with improved dermal compatibility containing monoglyceride (ether) sulfates and selected amino acid derivatives, to surface-active formulations containing these mixtures and to the use of the mixtures for the production of surface-active formulations.
2. Discussion of Related Art
Formally, monoglyceride sulfates are products of the addition of sulfur trioxide to the primary hydroxyl group of a glycerol monofatty acid ester. Technically, however, they are complex anionic surfactant mixtures which are normally obtained by the simultaneous transesterification and sulfation of mixtures of triglycerides and glycerol and subsequent neutralization.
Monoglyceride sulfates are distinguished by satisfactory performance properties and good dermatological compatibility. Overviews on the production and properties of monoglyceride sulfates have been published, for example, by A. K. Biswas et al. in J. Am. Oil. Chem. Soc. 37, 171 (1960), R. Chamanial et al. in J. Oil Technol. Ass. Ind. 41 (1972) and J. K. Jain in Indian J. Pharm. Sci. 41, 181 (1979).
Detergent mixtures containing gelatin in addition to coconut monoglyceride sulfates are known from U.S. Pat. No. 4,554,097 (Colgate-Palmolive).
Unfortunately, the foaming behavior, especially in hard water, and dermatological compatibility of monoglyceride sulfates and the corresponding ether sulfates are not entirely satisfactory for a number of applications.
Accordingly, the problem addressed by the present invention was to find a way of significantly improving the performance and dermal compatibility of monoglyceride (ether) sulfates.
DESCRIPTION OF THE INVENTION
The present invention relates to mild detergent mixtures containing ##STR1## in which R.sup.1 CO is a linear or branched acyl group containing 6 to 22 carbon atoms, x, y and z together are 0 or a number of 1 to 30 and X is an alkali metal or alkaline earth metal, and ##STR2## in which R.sup.2 CO is a linear or branched acyl group containing 6 to 22 carbon atoms and 0 and/or 1, 2 or 3 double bonds and X is hydrogen, an alkali metal and/or alkaline earth metal, ammonium, alkylammonium, alkanolammonium or glucammonium, acids containing 12 to 18 carbon atoms.
It has surprisingly been found that mixtures of monoglyceride sulfates or monoglyceride ether sulfates and the amino acid derivatives mentioned lead to synergistically improved dermal compatibility and increased foaming power.
Monoglyceride sulfates and monoglyceride ether sulfates are known anionic surfactants which may be obtained by the relevant methods of preparative organic chemistry. They are normally produced from triglycerides which are transesterified to the monoglycerides, optionally after ethoxylation, and subsequently sulfated and neutralized. The partial glycerides may also be reacted with suitable sulfating agents, preferably gaseous sulfur trioxide or chlorosulfonic acid [cf. WO 92/09569, WO 92/09570, Henkel KGaA]. If desired, the neutralized substances may be subjected to ultrafiltration to reduce the electrolyte content to the required level.
Typical examples of monoglyceride (ether) sulfates suitable for use in accordance with the invention are the reaction products of lauric acid monoglyceride, cocofatty acid monoglyceride, palmitic acid monoglyceride, stearic acid monoglyceride, oleic acid monoglyceride and tallow fatty acid monoglyceride and ethylene oxide adducts thereof with sulfur trioxide or chlorosulfonic acid in the form of the sodium salts. Monoglyceride sulfates corresponding to formula (I), in which R.sup.1 CO is a linear acyl group containing 8 to 18 carbon atoms, are preferably used.
Acyl glutamates are known anionic surfactants. They are produced, for example, by Schotten-Baumann acylation of glutamic acid with fatty acids, fatty acid esters or chlorides. Commercial products are available, for example, from Hoechst AG, Frankfurt, DE or from the Ajinomoto Co. Inc., Tokyo, JP. A review of the production and properties of acyl glu
